The study looked at how vegetation restoration in catchments on the Loess Plateau affected water and sediment behavior. They analyzed data from 1963 to 2011 and found that runoff and sediment decreased significantly over the years. The conversion of cropland to forest and grassland led to a decrease in runoff and sediment, especially during high flow periods. The volume of sediment completely disappeared in the most recent period studied. Overall, the project to convert cropland to forest and grassland helped save water and soil, increase base flow, and reduce runoff and sediment.
